  • Patent number: 9603214
    Abstract: A light emitting device (LED) array module includes at least one terminal, a light emitting device (LED) array, and a rank storing device. The LED array includes a plurality of LEDs that emit light when a current is supplied from the outside of the LED array module. The rank storing device is configured to store rank information of the LED array that depends on brightness characteristics of the LEDs, and to output a signal corresponding to the rank information via the at least one terminal.

  • Patent number: 9013188
    Abstract: Provided is an apparatus for sensing a failure that may apply, using a current control unit, a current to at least one first light emitting diode (LED) string and at least one second LED string that may be connected in parallel with each other, and as a result of sensing whether a failure occurs with respect to each of the at least one first LED string and the at least one second LED string, when a failure is sensed with respect to at least one of the at least one first LED string and the at least one second LED string, may transmit failure information to the current control unit, thereby blocking the entire current that may be applied to the at least one first LED string and the at least one second LED string, using the current control unit.
